How Long Does Thermal Paste Take To Dry?

When installing a CPU cooler, one of the first things to do is apply thermal paste. This is done by applying it in its thin form but spread evenly on the CPU. While it can be frustrating to wait for the thermal paste to dry before putting on the cooler, it will actually help give your computer more stability. This blog will help you to know how long does the thermal paste take to dry?

An article on thermal paste may seem pointless, but there are a few things you may not know about this product. Firstly, thermal paste’s main purpose is to fill the gap between the processor and the heat sink. Without this gap filled, heat would not be effectively transferred from the processor to the heatsink which could cause serious damage to your computer.

In addition, thermal paste helps with heat transfer by increasing thermal conductivity by about fifty times more than air alone.There are many reasons that someone might want to know how much value thermal paste provides.

Some people use it when they are trying to solve overheating issues, while others use it when they are in the process of installation. One might also be in need of it in order to replace an old tube of thermal paste in their computer.

What Is Thermal Paste?

Thermal paste is a silicon-based compound that is used to fill in microscopic air gaps on a CPU. It is often used on these chips to transfer heat from the solder joints and spread it evenly across the die. Thermal paste’s material properties have a low thermal conductivity, so it is usually only used as a supplement to heatsinks for CPU cooling.

It provides laptop tech support and makes it stable for years due to thermal compound protection and enhances the shelf life of the device. Acer laptop overheats quickly and hence it is the right choice for it.

How To Apply Correctly?

Applying thermal paste correctly is an important part of any computer. In order to apply the thermal paste properly, you need to follow a few easy steps.

First remove the old particles from the surface of your CPU and motherboard by scrubbing with rubbing alcohol on a cotton swab.

Next, apply a thin layer of new thermal paste on the surface of both your CPU and motherboard following the manufacturer’s instructions on the package.

How Long Does Thermal Paste Take To Dry?

It is essential that the thermally conductive compound Or thermal grease between the CPU and its heatsink is kept in place at all times to maintain an efficient thermal interface. Applying too much paste can lead to a situation where it will never dry, while not applying enough can result in a failed installation.

The amount of time it takes for the paste to dry depends on factors such as the type of thermal paste, ambient humidity and air flow. Different types of thermal paste take different time. It is better to leave it for one hour or two hours for a layer of thermal compound.

It is better to check the leakage of the system by paper towel test. Place the paper towel over the layer if the liquid paste seeps out then there is some mistake or small imperfections in the system that needs correction. Too much amount of the thermal paste causes a high level of thermal resistance, so it is a good idea to use only a small and appropriate amount.

Liquid paste is good choicer than non-metallic compounds as the other one get cracks with in month due to hot air from  CPU heat and also damages the other parts of the computer due to high temperature and heat of laptop fans.


Thermal paste is a thermal compound that helps transfer heat from one surface to another. When it comes to time, the best way to let thermal paste dry is for it to sit overnight or until you can no longer smell anything. This also means there should be no harm in taking the next couple of days off as well since it will take a while for the paste to dry.
